Specification of Letters Patent.

Application filed May 25. 1906. Serial No 318.631.

To albwhmn it may 'concern:

Be it known that I, WILLIAM D. Bmw, a

V citizen of the United States, residing at New Brighton, in the county of Beaver and State I of Pennsylvania, have invented a new and useful Improvement in Bosh-Plates, of which the following is a specification.

I This invention relates to what is known as bosh-plates l for blast-furnaces and the like and the object is to provide a plate of this' kind in which thewater circu'lating through the same is so directed as to project the cold i water against the whole inner end or nose of` the plate and also to'keep the dirt and sedirrient from collecting at the corners of the ate. P The invention comprises an arrangement 'of arts hereinafter described and claimed.

n the accompanying drawings, Figure 1 is in part a plan view and in part a horizontal section of the plate. Fg. 2 is an outer end view of the same. Fig. 3 is a longitudinal section on the line 3 3, Fig 1. Fig. 4 is a transverse section on the line 4 4, Fig. 1; and Fig. 5 is a similar section on the line 5 5, Fig. 1.` i p This platewillbecast of any suitable metal, preferably bronze or cop er, as isnow the case, and is formed as a ollow .or recessed 'body 1 of substantially the shape shown, be-

ing tapered from its outer end 2 in both directions', so as to form a natural ,stifi support for the masonry. The lower face of the plate 4 is preferably substantially straight, while its upper face 5 is arched, 'but on straight lines, as shown, said lines changing direction at the points 6, so as to form a series of flat plate, and at each end with cleaning-openings walls for directing an r 11, normally closed by suitable plugs. (Not shown.)

The body of .the plate is hollow, as is the usual custom, and is rovided with suitable i distributing the flow of water. The inlet-opening 9 communic'ates with a passage 14, eXtending along the I bottom of theplate toward the front end thereof, this passage at its rear portion being for only about half the height or thickness of the plate, as shown in Fig. 3, and then deepening to the full height or thickness of the plate and its front or forward end spreading out to form the wide distributing-charnber 16. This distributing-chamber 16 is separated from a passage or chamber 17 in the noseof the plate by a wall 18, provided with perforations 19, so as to direct the water in jets or streams against the front or nose wall 20 of the plate. The openings are shown as oblong vertically, Fig. 2; but obviously they may be ofsany desired shape. In the distributing-chamber 16 is a suitably-curved or double inclined deflecting member 21, which causes the cold water coming through the passage 14 to be divided and directed toward both sides of the plate. Consequently cold water is directed against all portions of the nose-wall 20 of the plate, thus keeping it as cold as possible. Furthermore, the water being directed in jets against said wall prevents the de osit of dirt and other sediment and especial y at the angles 22 at the front corners of the plate.

The water directed against the nose-wall of the plate flows backwardly on each side in the side passages 23 and then is directed in a circuitous path by the baffle-walls 24 and 25, and finally reaches the outlet-opening through a passage 26 located above the rear end of the inlet-passage 14 and whose front end is defined by the curved transverse wall 27, running to the top wall of the plate.

The plate is made by casting and coring in the usual way. By the Construction shown cold water is directed against the whole front surface or nose of the plate, and the flow of the water is such that the deposit of dirt or sediment,` and especially at thefront corners, is prevented. The plate can be readily. cleaned when necessary through the cleaning-openings 11. pered or arched in straight lines facilitates the laying of masonry on the same. This plate can be applied in any way of applying prior forms of bosh-plates.

What I claim isp 1. A bosh-plate comprising a recessed body having inlet and outlet openings, a passage from the inlet-opening toward the nose of the plate, and a spreader at the forward end 'of the passage arranged to divide the stream and direct the same toward both sides. i

2. A bosh-plate comprising a recessed body having inlet and outlet openings, and a The top b eing ta- IOO nose of the plate and ending in a laterallyenlarged distributing portion separated from the nose ofthe late by a perforated wall.

3. A boshlato oomprising a reoessed body having nlet and outlet openings, the inlet-opening oommunioatng with a passage extendng toward the nose of the plate and ending in a laterally-enlarged distributingoharnber, a perforated wall between said chamber and the. nose-wall of the plate, and

aspreader in said .ohamber opposite the end of the passage coming from the inlet-opening.

4. A bosh-plate oonprising a reoessed ;body having inlet and outlet openings arranged oentrally oftheplate, 'saidnlet-opening\oomInunioati-n g With a passage :eXtending :toward .thenose of the plate, other assages ;located-wat the-sides ofthe plate an leading from the nose portionof the late, and baffie-walls extending ;longitu inally -of the `plate and fornng circuitous passages from the side passages to the outlet.

5. A boshplate comprising a reoessed body having inlet and outlet openings, said inlet-o ening communicating with a passage eXten ing oentrally of the plate toward the front end thereof and ending in a laterallyenlarged distributing-oharnber, a perforated ,near ts central portion .and washout-openings near each si e, and having a battle-wall on each side forming With the side 'Walls restricted passages :and extending from the washout-openings 'to the :front corners 'of the `plate.
